Best configuration for Magento servers:

1. PHP >= 5.4
2. Flat catalog (if this is possible)
3. nginx + php5-fpm
4. opcache/apc
5. Percona for database
6. Redis for session
7. Varnish
8. Solr for search (build in enterprise)

For server You can choose some cloud environments (for example Amazon EC2), than if you need more power for particular moment (e.g. Easter) you can scale whole environment. Another good practice is separating the application and database servers.
